Thomas Sowell on the ‘Man-Made Global Warming’ Scam

One of the world's most respected scholars, Thomas Sowell, on the "man-made global warming" scam:

"Temperatures went up first, and then there was the increase in CO2. You can't say that A causes B if B happens first... But [the scientists] who are pushing global warming are doing their damnedest to make sure that those who believe the opposite don't get heard in the public."
